At the construction site of an expressway in southern China, XCMG's driverless cluster road equipment is operating in an orderly manner. It is understood that this is the largest unmanned cluster paving and maintenance construction in the world so far, the first unmanned maintenance construction application of the highest grade pavement in China, and the first unmanned cluster intelligent maintenance on the operated expressway, which is of great significance. 10 XCMG driverless double steel wheel rollers and 2 XCMG large width pavers use innovative technologies such as high-precision Beidou Positioning, inertial navigation, obstacle identification and multiple safety design to overcome the constraints on construction caused by extreme weather and special terrain. In recent years, under the background of the application of new generation information technology such as artificial intelligence, 5G digital, XCMG has effectively reduced costs and increased efficiency through digital upgrading, effectively offsetting the cost rise caused by the substantial growth of raw materials, shipping and other logistics this year.
